8T0? MGTION' CARD-TABULATINGMACHINES.

Application filed September 13, 1917. Serialfio. 191,155.

To all whom it may concern a citizen of the United States, residing in borough of Brooklyn, in the county of Kings, city and State of New York, have invented certain new and useful Improvements in Stop Motions for Card-Tabulating Machines, of which the'i'ollowing is a specification.

The object of my invention is to provide a new and improved stop motion mechanism" for use in eard-tabulatingmachines, by'the use of which when certain series of tabulating cards have passed through the tabulating card machine, and the last card of each' of such individual series passes through the machine the same will be automatically stopped, and be prevented from further operation and recording until anew series of cards is inserted in the machine.

My invention herein disclosed described and claimed while not limited thereto relates primarily to tabulating machine mechanisms.

mechanism which stops the machine, upon a break inthe series of cards should be located at some little distance from the cardfeeding mechanism; it is also absolutelyes cards; in other words it is absolutely essential in the proper manipulation of the machine that immediatelyupon the passage of the last card of each individual series, there should be'no further actuation of the tabu- 40 lating mechanism, until the insertion of another series of cards.

To such ends my invention consistsprimarily, and in broad substance, of? an automatic stopping trip-mechanism which will and recording mechanism against furt er movement immediately upon the. passage of the last card of any given series or failure of an intermediate card of a .series to be fed, thru so the tabulating mechanism; which tripping and stopping mechanism is preferably but not necessarily connected with the card-feeding mechanism of the tabulating machine by a flexible-connection, so as to save weight In machines of this character, it is fre-' quently necessary that the feed "stopping and valuable working-space adjacent to the tabulator and recorder.

My. said invention is fully shown de-. scribed and claimed, in the following specification, ofwhich the accompanying drawings form a part; wherein similar letters or numerals or references, designate like or equivalent parts throughout the several views, and in which 1 Fig. 1 is a top plan-view in perspective, and-indetail of my improved tabulating machine-stop mechanism.

{not shown) mounted upon a r-evciulclesha it l6 l meshing with endiess' screw nan (not shown) carried by the shaft 12, by which said shaft 16 is rotated. And rigidly secured to or formed integral with the shaft l6, of the worm-wheel is a throw-lever 1's",

engageable with the end portion 18, of the reciprocating stop-plunger 19, rigidly secured to or formed integral with said end portion 18 and the like shaft 18'". The stop plunger 19 is provided with the annular peripheral screw-threaded shift-slot 26-, in

.which works the end of the shift-screw 21,

passing thru the side wall of the stop-journal slip-chamber of the housing 5, usually and preferably formed integral with the main ear-wheel 22 revolubl su orted s 3 PP shaft 16 passes, while at the other end the shaft 18', passes out thru and is revolubly journaled in the wheel 22, and is provided at its outer end with the small gear-wheel 25, rigidly secured thereto. Concentrically mounted upon the shaft 18 between the slip stop plunger 19, and the wheel 22, is the helical or coil spring 26, one end of which fits into a journal-box or perforation 27, formed to receive it in the wheel 22 while the other like end fits in a like journal-box perforation, in the stop-journal or plunger 19; the tension of said spring 26 serving to normally keep the shaft 18, thrust outward as indicated in Fig. 2 in dotted lines so as to contact with the throw-lever 17 of the shaft 16; whereby it will be seen that the rotation from the top toward the front of Fig. 2, of such shaft 16, will-by the contact of said lever 17, with the end-shaft 18, cause a rotation of the wheel 22 carrying with it the wheel 25, in the same direction, as clearly indicated by the arrow in Fig. 4:.

Vibratorily supported upon the pivotshaft 35, supported in the side-wall of the frame'A, is the stop trip-lever 36, supported against side displacement in a slot 37, of a hollow supporting-stud 38, within which is a helical or coil-spring 39, normally pressing the outer free end of such vibrating triplever 36 upward. Immediately above the spring 39 the trip-lever 36 is provided with the segmental rack-gear 45, adapted when such trip-lever 36 is thrown upward to mesh with'the gear-wheel 25 in such manner that the continued rotation of the wheel 22 will cause the rotation of such gear-whee125 and its shaft 18 (as clearly indicated by mes es the arrows in Figs. 2, 3, and a) so as to, by the action of the stop plunger 19 upon the screw 21 draw back said stop plunger 19 and the shaft 18 against the tension of the spring 26 into the position shown in Fig. 3 so as to draw the outer end of the shaft 18 out of contact with the throw lever 17, carried by the shaft 16 and also to exert a positive braking action against the frame A; whereupon the rotation of the gearwheel 22 will be instantaneously stopped.

The trip vibrating lever 36, is locked in place, in its lowered position shown in Fig. 5, by bell crank or detent lever 46, pivotally mounted on the pivot-screw 47 and normally pressed upward into the locking position shown in Fig. 5, by the spring 48 in the slotted socket stud 12.

@n the other end of the trip-lever 36, and integrally formed therewith is the lock-lug 50 having located in the space 51 the throwpin 52 of the release lever 53, pivotally mounted. on the stud shaft 54-, adjacent to which is also pivotally mounted on the stud shaft 55 the bell-crank lock-lever 56, normally forced into the locking position shown 'in Fig. i by a helical or coil spring 57 secured at one end to the lock-lever 56: and at the other to the frame A. The lock-lever 56 is provided with the lower slide-face 56, which upon the movement of such lever rides up and down over the lower throw-pin 52,

of lever 53 and ends at the top in a horizontal catch-surface 59, which engages with the lock-lug 50 when the vibrating racklever 36 is automatically thrown up into en- I gagement with the release gear wheel 25 by the spring 39 as shown in Fig. 4; so as to lock such rack-lever 36 against accidental displacement.

Connecting this before mentioned release mechanism with the card sortingand tabulating machine, is any suitable mechanismfor unlocking the trip-lever 36, whenever no tabulating card is in position under the tabulating mechanism. I

The connect ng mechanism connecting said tabulating iLIICllQCO-IQllllg' mechanism and my improved stop-mechanism therefor, may be of manyand varied forms, but when, as is usually the case, the stop mechanism is located some distance from the card-sorting and tabulating card actuated mechanism, I prefer to use the mechanism shown, wherein the reference numeral 60 designates a hollow flexible-connecting coil of any suitable form such as braided or woven wire, or other suitable material, the. upper end of which is secured to a suitable support 61, supported in any suitable manner upon the main-frame (not shown) of the card tabulating and recording machine, the lower end of which hollow coil is provided with a solid metallic sleeve 62, secured by screws 63, to the side wall of the frame A, all as clearly indicated nseaeee in Fig. 4%. Through the flexible connecting coil 60, easily reciprocates flexible-plunger 65, usually of highly tempered steel wire, the lower end of which is adapted when such wire 65, is forced downward to contact with the, horizontal trip end-member d6, of the bell-crank lever 46, so as to force such bellcranl: lever 46, against the tension of the spring 48, down into the unlocking position shown in Fig. l, so as to release the triplever 36, and permit the same to be forced upward by the spring 39, with its rack 45 thrown into mesh with the release small gear-wheel 25, carried by the gear-wheel 22 (as shown in Fig. l).

I have not deemed it essential herein. to show the card feeding and tabulating mechanism in ful but only a slight portion thereof; but in the card tabulating machines of the particular form with which my improved stopping velicle is designed to be used, the perforated cards designated by D, as shown in Fig. 6,are by suitable mechanism {not shown) fed from the front said Fig. 8, toward the rear, over a supporting card-table or plate 67, and as each card comes into proper tabulating position upon said plate or table 67, tabulating-plungers. not shown) are forced through what perforations are in the particular card which is in position to have its data recorded, by the tabulating and recording mechanism machine; such recording and tabulating mechanism being put into recording and tabulating operation by such plungers, as are passed through per forations in the card.

Supported above the table a vertical shaft 68 upon which reciprocates a slip-sleeve 69, carrying a stop-pin 70 passing through the plate 67, and the stud 71, formed integral with the slip-sleeve or journal 69, and also passing through and secured to a. throw-lug 72 having rigidly secure-d therein a feeling device or detector plunger 73, in registry with a perforation in the card-plate table 67, which throwdug 72 reciprocates up and down thru a journal bar 74, formed integral with or mcured to the-standard or shaft 68, and between the lugs 71 and 72 is interposed a spring 75 usually of the helical coil form shown'.

As the slip sleeve 69,is lifted upward, at the same time (and by mechanism not shown and which forms no part of my present invention) the cards D are one by one automatically fed under the feeling device or detector plunger 7 8, and upon the downward movement of 69, such feeling device or detector plunger 73 is stopped from passing through the plate or card table 67, by impingement upon the card, as clearlyin dicated in Fig. 6; when however, the last card of any particular series has passed, and no card is in place beneath the plunger 73 (as indicated in Fig. 1 at the or plate 67, is

top and right) such plunger 73 passes through I the-perforation in the card table '67, and carries with it the stop-pin 70, which impinges upon the top end of the reciprocating stop wire 55, and forces it down through 61, 60, and 62, upon the rear end 46' of the bellcranlz lock-lever at so as to force such lever down into the unlocking and releasing position shown. in Fig. i, against the tension of the spring as, whereupon the spring 3%) will throw lever 36, up into mesh with the gear wheel 25, and the continued rotation of the wheel 22 will draw out the shaft 18 against the tension of the spring 26 into the position shown inl ig. 3, into nonengagement with the throw-lever l7 rigidly secured to the shaft 16, whereupon the tabulating and recording mechanism will be instantaneously, stopped until such time as by the throwing upward by hand, (upon the insertion of the first of a new series of cards) of the lever 53, the vibrating segmental rack-lever 36 will be thrown downward against the pressum of the spring 39, into the running position shown in Fig. 5 and this operation is repeated between each particular series of cards being tabulated and recorded.

It is evident that many changes and modifications'in the particular construction, combination, and arrangement of the several parts of my improved mechanism for automatically stopping, card tabulating and recording machines, upon the failure of a card to pass beneath the recording and tabulating mechanism herein shown and described may be made, without departing from the scope of my invention.
